div - compute the quotient and remainder of an integer division
div_t div(int numer, int denom);
The div() function shall compute the quotient and remainder of the division of the numerator numer by the denominator denom. If the division is inexact, the resulting quotient is the integer of lesser magnitude that is the nearest to the algebraic quotient. If the result cannot be represented, the behavior is undefined; otherwise, quot* denom+ rem shall equal numer.
The div() function shall return a structure of type div_t, comprising both the quotient and the remainder. The structure includes the following members, in any order:
int quot; /* quotient */ int rem; /* remainder */
No errors are defined.
